Among these settings are capabilities, which give fine-grained control over the actions processes within a container can perform. Now, let's delve deeper into Kubernetes SecurityContext Capabilities through a simple lesson.

INTRODUCTION In Kubernetes, a Pod can host multiple containers that form a single unit of deployment. These containers share the same network namespace, which means they can communicate with each other using ‘localhost’ and share the same IP and port space. Multi-container pods encapsulate multiple containers into one single deployable…
